TITLE: Football, basketball and soccer. LAB GOAL: Determine the impacting force on different athletic balls. Compare throwing a football, kicking a soccerball and shooting a basketball.
PROCEDURE:
1.)Mass the athletic ball(football, basketball, soccer). Once massed convert grams into kilograms.
2.)Record video of althletic activity. In video hold meterstick perpendicular to the camera. Then procede with the activity.
3.)Upload video onto computer and open Loggerpro.
4.)On Loggerpro click "insert" and scroll down to "movie" to upload your video.
.
6.)Begin clicking on the same point on the ball.
7.)When your finished recording the dots throughtout the ball's motion, observe the "X Velocity" graph and "Y Velocity" graph.
8.)To find the average slope of both velocities click "data" and scroll down to "new calculated column".
To get equation:
-Press Functions>sqrt,
-Press Variables(Columns)>("X Velocity"^2+
-Press Variables(Columns)>"Y Velocity"^2)
-Press done. 10.)Click "insert" and scroll to graph.
11.)The tab will show you the average slope(m/s/s). The slope is equal to the average acceleration(m/s/s).
12.)To find the force impacted on the ball, take the acceleration(m/s/s) and multiply by the balls mass(kg).
REFLECTION: Every athletic activity calls for a different amount of force used on the activities athletic ball. By taking three completely different sports like football, basketball and soccer we were able to compare the amount of force used. To find the force of each activity we used "Acceleration=force/mass". We found that soccer had the highest amount of force, basketball had the lowest amount of force and footballs amount of force fell inbetween. Soccer's force is 47.76 N, basketball's force is 2.87 N and football's force is 17.389 N. There are many factors that can affect or alter our data. While playing any sport the force depends on the extent at which the individual preforms the activity. For example, in basketball the force would differ if a 3-pointer was shot rather than a free throw. Comparing the three sports showed us how the force differs depending on the sport. Seeing the results sparked some confusion but ultimately more interest! We were shocked when we found out that basketball had the lowest amount of force. In the future we want to expand on this experiment to find out what factors affect the force in all three sports. By using something that we are interested in like sports we were able to apply physics into our everyday lives.

3.)Upload video onto computer and open Loggerpro.
4.)On Loggerpro click "insert" and scroll down to "movie" to upload your video.
5.)Watch the video. When your done watching, rewind the video to the beginning. Select "yellow ruler" button
6.)Begin clicking on the same point on the ball.
7.)When your finished recording the dots throughtout the ball's motion, observe the "X Velocity" graph and "Y Velocity" graph.
8.)To find the average slope of both velocities click "data" and scroll down to "new calculated column".
9.)On "new calculated column" fillow out table as shown below.
To get equation:
-Press Functions>sqrt,
-Press Variables(Columns)>("X Velocity"^2+
-Press Variables(Columns)>"Y Velocity"^2)
-Press done.
10.)Click "insert" and scroll to graph.
10.)Highlight the main change in velocity on the "Velocity" graph and press the "linear fit" button.
11.)The tab will show you the average slope(m/s/s). The slope is equal to the average acceleration(m/s/s).
12.)To find the force impacted on the ball, take the acceleration(m/s/s) and multiply by the balls mass(kg).
DATA:
Football:
Slope=Acceleration. Acceleration=force/mass
Slope=52.08m/s/s
Mass=.334kg
52.08=force/.334 Force=17.39N
Basketball:
Slope=Acceleration. Acceleration=force/mass
Slope=4.973m/s/s
Mass=.578kg
4.97=force/.578 Force=2.87N
Soccer:
Slope=Acceleration. Acceleration=force/mass
Slope=120.0m/s/s
Mass=.398kg
120.0=force/.398 Force=47.76N
